1. Field
The present disclosure relates to packaging for a coil of wound material. More particularly, the present disclosure relates to a barbed locking ring for securing a tube to a container that holds a coil of wound material that is to be dispensed through the tube.
2. State of the Art
U.S. Pat. No. 2,634,922 to Taylor describes the winding of flexible wire, cable or filamentary material (hereinafter “wire”, which is to be broadly understood in the specification and claims) around a mandrel in a figure-eight pattern such that a package of material is obtained having a plurality of layers surrounding a central core space. By rotating the mandrel and by controllably moving a traverse that guides the wire laterally relative to mandrel, the layers of the figure-eight pattern are provided with aligned holes (cumulatively a “pay-out hole”) such that the inner end of the flexible material may be drawn out through the payout hole. When a package of wire is wound in this manner, the wire may be unwound through the payout hole without rotating the package, without imparting a rotation in the wire around its axis (i.e., twisting), and without kinking. This provides a major advantage to the users of the wire. Coils that are wound in this manner and dispense from the inside-out without twists, tangles, snags or overruns are known in the art as REELEX- (a trademark of Reelex Packaging Solutions, Inc.) type coils. REELEX-type coils are wound to form a generally short hollow cylinder with a radial opening formed at one location in the middle of the cylinder. A payout tube may be located in the radial opening and the end of the wire making up the coil may be fed through the payout tube for ease in dispensing the wire.
Over the past fifty-plus years, improvements have been made to the original invention described in U.S. Pat. No. 2,634,922. For example, U.S. Pat. No. 5,470,026 to Kotzur describes means for controlling the reciprocating movement of the traverse with respect to the rotation of the mandrel in order to wind the wire on the mandrel to form a radial payout hole having a substantially constant diameter. In addition, over the past fifty-plus years, an increasing number of different types of wires with different characteristics are being wound using the systems and methods described in U.S. Pat. No. 2,635,922 and the subsequent improvements. For example, the figure-eight type winding has been used for twisted-pair type cable (e.g., Category 5, Category 6 and the like), drop cable, fiber-optic cable, electrical building wire (THHN), etc. Despite the widespread applicability of the technology, challenges remain in applying the technology to different wires.
In one embodiment, a locking ring is provided that permits dispensing of filamentary material housed in a walled container through a payout tube defining a payout tube axis and through which a first end of the filamentary material extends. The ring includes an annular flange around a ring axis and a body having a tubular wall extending from an inner edge of the annular flange to a distal edge of the ring. The tubular wall is coaxial with the ring axis, and has a plurality of teeth circumferentially spaced around the tubular wall that extend from the tubular wall radially outwardly and toward the annular flange. The teeth have curved edges that are curved about the ring axis and an axis perpendicular to the ring axis. The curved outer surface is curved about the ring axis. Each tooth resiliently deflects radially inwardly in response to interference between a curved outer surface of the tooth and an inner wall of the payout tube. Each tooth may have a barbed edge that digs into the inner wall of the payout tube when the tooth is engaged with the inner wall of the payout tube. The teeth may be equally spaced circumferentially.
The body may have a plurality of circumferentially spaced ribs, where each rib extends longitudinally along the outer side of the tubular wall of the body. Each rib may be circumferentially spaced between two of the teeth. The ribs may be equally spaced circumferentially.
Each rib may be defined by a peak, a first tapered portion extending from the peak towards the distal edge, and a second tapered portion extending from the peak towards the flange. The first tapered portion may be angled at a first angle with respect to the outer side of the tubular wall of the body and the second tapered portion is angled at a second angle with respect to the outer side of the tubular wall of the body. The first angle may be larger than the second angle. Also, the first tapered portion may be spaced axially from the distal edge of the body. The first tapered portion of each rib may be constructed to align the ring axis of the locking ring with the axis of the payout tube when the distal edge of the body is introduced into the payout tube and the payout tube contacts at least one first tapered portion.
In another embodiment, an assembly is provided that includes a wound coil of filamentary material having a first end, a payout tube extending from an inside of the wound coil to an outside of the wound coil along a payout tube axis with the first end of the filamentary material extending through the payout tube. Also, the assembly includes a box containing the wound coil and payout tube. The box has a side wall defining a first hole and a second hole. Further, the assembly includes a locking ring having an annular flange around a ring axis and having a body having a tubular wall extending from an inner edge of the annular flange to a distal edge of the locking ring. The tubular wall is coaxial with the ring axis and the body extends through the first hole of the box and is received in the payout tube.
The tubular wall has a plurality of teeth circumferentially spaced around the tubular wall, each tooth having an outer edge curved about the ring axis and about an axis perpendicular to the ring axis. The teeth are capable of being resiliently deflected radially inwardly by interference between an outer curved surface of each tooth and an inner wall of the payout tube. The outer curved surface is curved about the ring axis. An outer side of the wall is frustoconical and the outer side of the wall has a smaller diameter at the distal edge than at the inner edge of the annular flange. In one embodiment, each curved outer edge of each tooth threads with the payout tube in a first rotational direction to secure the side wall of the box between the annular flange and the payout tube.
In another embodiment a method for packaging a wound coil of filamentary material for dispensing is provided. The method includes disposing a payout tube in the wound coil of filamentary material and introducing a first end of the filamentary material in the payout tube where the payout tube extends along a payout tube axis. Also, the method includes inserting the wound coil of filamentary material with the payout tube into a box and pulling the first end of the filamentary material through a first hole defined in a side wall of the box. Further, the method includes inserting a ring around the first end of the filamentary material and into the hole of the box and into the payout tube. The ring has an annular flange around a ring axis and a body that has a tubular wall extending from an inner edge of the annular flange to a distal edge of the ring. The tubular wall is coaxial with the ring axis. The wall has a plurality of teeth circumferentially spaced around the wall and extend from the wall radially outwardly and toward the annular flange. The body is constructed for relative axial movement within the payout tube. Each tooth is constructed to resiliently deflect radially inwardly in response to interference between an outer curved surface of the tooth and an inner wall of the payout tube. An outer side of the tubular wall is frustoconical, and the outer side of the tubular wall has a smaller diameter at the distal edge than at the inner edge of the annular flange.
In one aspect the curved edges of the teeth form a thread that permits the locking ring to advance axially into and secure with the payout tube when the teeth are engaged with the inner wall of the payout tube and are rotated in a first direction with respect to the payout tube.
